Process for polymerizing olefins in the presence of a catalyst prepared from organomagnesium compound, organic hydroxyl-containing compound, reducing halide source and transition metal compound

摘要

Olefins are polymerized in the presence of, as a catalyst therefor, the unseparated catalytic reaction product resulting from heating a mixture of (A) at least one hydrocarbon soluble organomagnesium material; (B) at least one organic hydroxyl-containing material; (C) at least one reducing halide source; and (D) at least one transition metal (Tm) compound.
